Roll forming is a continuous process that has distinct advantages over other production methods. It eliminates multiple stage production, finishing or sub-assembly operations.
Secondary operations can be combined continuously with the roll forming operation to speed production and reduce assembly costs. Roll forming permits consistent adherence to close tolerances and provides uniform shapes and dimensions to fit customers’ specifications.
The ability to fabricate decorative parts from pre-coated, pre-painted, or pre-plated metal is a distinct feature of roll forming.
Practically all metals can be roll formed, not just aluminum, which is a distinct advantage of roll forming compared to extrusion methods that also require multiple stage production methods. Operations such as notching, punching, and post-painting can be eliminated by using roll forming.
